MCP should not mean letting AI touch your database

Short summary

MCP tools should call documented HTTP APIs, not direct databases. Design layered architecture: agent → MCP → API → handler → use case → repository. Start with read tools; design write tools with full security (auth, validation, audit logging).

• •MCP tools must respect application boundaries—call HTTP APIs instead of direct database access
• •Implement layered architecture with explicit authorization, validation, and audit logging
• •Start with read-only tools; design write tools with production-grade security controls and error contracts
